A credible friend, who is on the academic team at my high school, was telling me that reason ocean make us feel calm is because we are high the ozone... This is the first I've heard of it and I can't find any info online. Does anyone have any real input to this? Not just answers like "yes." or "no." or "thats crazy". 10 points someone who knows what the heck they're talking about!

After playing a multi-player fps game and getting sniped by an enemy sniper several times I got really pissed of....,

Could there be a device which detects the sniper position before he gets his first shot? I believe the radar doesn't work on a sniper, cause they track only moving targets

This might be stupid, but this is the only place to ask anything, so just read it..

could there be a device which spits out charged particles( robots) in all directions like a radar. When the particles hits and accumulate on a human(lens of eye) it lights up and sends some kind of a signal back to our device and notify about the presence of the sniper???

I know its logical, but is it practical?

Is it possible that memory from a donor, no matter how small is transferred to its clone? Is there any scientific paper on the subject out there?

Did you know that 80% of UCSD students
could not find the error above? Re post
this with the title "find the error, its impossible"
and when you click "Submit Post", the
answer will be really obvious.





this was on a bulleting, but was it really an error or not?

In the United States, alcohol is rated according to "proof" which is usually defined as twice the percent by volume of pure ethanol in solution, measured at 60*F. What is the molarity of ethanol in a "92 proof" solution of ethanol in water. The density of ethanol (C2H5OH, molar mass=46g/mole) is 0.80g/cm^3 at 60*F; the density of water (H2O, molar mass= 18g/mole) is 1.0 gm/cm^3 at 60*F(15.5*C) Please Explain
